CAN-COVER.

SPECIFICATION forming part of Letters Patent N 0. 572,471, datedDecember 1, 1896. Application filed Febr ary 11, 1896. Serial No.578,872. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. BURNHAM, a citizen of the United States,residing at Minneapolis, in the county of Ottawa and State of Kansas,have invented certain new and useful Improvements in Can-Covers for Milkand Cream; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in cansand covers therefor, designed especially for the reception andtransportation of milk or cream; and it has for its objects, amongothers, to provide a simple and cheap construction whereby cream can bekept from slopping and moving about and churning in the can duringitstransportation.

The invention embodies a cover with means whereby it may be secured atany point within the can, according to the height of the milk or creamtherein, and having provision for allowance of the escape of 'air.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theappended claim.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a central vertical section of myimproved can with the cover in elevation. Fig. 2 is a top plan of thecover.

Like letters of reference indicate like parts in both views.

Referring now to the details of the drawings by letter, A designates thecan, which is of uniform diameter throughout its entire height, so thatit can be more readily cleaned and the cover readily moved therein toany desired height.

Bis the cover, having, preferably, a conical top with a screw-threadedneck or nipple b, adapted to receive the screw-cap C, so as toeffectually close the same when desired. This cover has adepending-flange l3 fitted to move readily within the can. The cover isprovided with suitable handles D, by which it may be manipulated andarranged. The upper edge of its depending flange has an .expansible bandE, which may or may not have secured thereto a band B, of rubber or somesimilar material, so that the cover may be made perfectly tight at anypoint in the can from the top to the bottom, and this band E is designedto be expanded by means of a screw or thumb bolt G, passed through theinternally-threaded ears 9 at the ends of the band. This band isseparate from but applied above the flange of the cover.

In practice the cover is placed Within the can and pushed down into therequired height close onto the cream, the screw-cap being removed, so asto allow of the escape of the air. When the cover is in the desiredposition, it is there fastened by turning the screw-bolt, so as toexpand the band and cause it to engage frictionally all around with theinner wall of the can, and the cover is held down upon the cream ormilk, so as to prevent the same from slopping or splashing and churning.WVhen it is desired to remove the cream, all that it is necessary to dois to move the screw-cap, when the cream can be poured into openings inthe top of the cover, or by loosening the band the entire cover may beremoved. I 8o Modifications in details may be resorted to withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

Having thus described the invention, what is claimed as new is- 8 5 Thecombination with the can, of a cover having a depending flangefittedwithin said can and provided with an opening in the top thereof with aclosure therefor, an expansible band mounted on the upper edge of thecover and having ears extending at right angles therefrom, a screw-boltthreaded in the said ears and an elastic band around the outer surfaceof the expansible band, all substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
